When you query the SYS.DM_EXEC_QUERY_PROFILES DMV to examine an execution plan that references tables that contain many rows (more than 232), the DMV may return an incorrect number of rows in the “estimate_row_count” column of some operators, capping the value at 232.

Note Neither the estimated query plan or live query statistics are affected by this issue.


This issue occurs because the “estimate_row_count” column is internally handled as a 32-bit value. For values greater than 232, Microsoft SQL Server limits the column to 232.


This fix is included in Cumulative Update 2 for SQL Server 2017.
